If you want long battery life and ANC headphones for nurses, choose iClever BTH20; if you need broader audio options and app controls, choose 1Mii E700. The BTH20’s 47.5-hour battery figure and included 3.5 mm cable make it the more flexible routine pick, while the E700 adds hybrid noise cancellation and app-based settings. Neither is an on-ear model or a true wireless earbud; both are over-ear headphones.
iClever BTH20 vs 1Mii E700 at a Glance
• iClever BTH20 strength: 47.5 hours of stated battery life, Bluetooth 5.4, active noise cancellation, and included wired listening through a detachable 3.5 mm cable. Trade-off: its listed controls are button-based, without the app options specified for the E700.
• 1Mii E700 strength: hybrid active noise cancellation, app and button controls, and a 54-hour battery figure. Trade-off: its listed wired connection uses USB Type-C rather than a standard 3.5 mm headphone jack.
• Both models are over-ear, Bluetooth headphones with 40 mm dynamic drivers and USB-C charging.
• Choose the BTH20 for a long-running, straightforward headset with a familiar wired fallback; choose the E700 for hybrid ANC and more ways to adjust settings.
The iClever BTH20 makes sense for someone who wants a single over-ear pair for wireless listening and occasional wired use. Its Bluetooth 5.4 connection is listed with a 10-meter range, and its 3.5 mm jack gives you another way to connect when Bluetooth is not the preferred option. The detachable cable is included, so wired listening is part of the package rather than an add-on to seek out separately.
Battery life is a notable part of its appeal. The listed average is 47.5 hours, with a two-hour charging time. That combination can suit long stretches between charging sessions, whether the headphones are used during a commute, while traveling, or at home. Active noise cancellation is included, but the product information does not specify different ANC modes or app adjustments. The controls are push buttons, which points to a simpler approach rather than a settings-heavy one.

Who should skip it: Skip the BTH20 if app-based ANC adjustments or hybrid noise cancellation are priorities; those features are not listed for this model.
The 1Mii E700 is the more feature-oriented choice. It combines active and hybrid noise cancellation with controls through both buttons and an app. The product information also lists voice assistant, call, noise, and volume controls. That gives buyers more ways to manage listening than the BTH20’s listed push-button setup, although it also means the E700 is a better match for someone who actually wants those options rather than a bare-bones headset.
Its stated average battery life is 54 hours, and its charging time is three hours. That is a longer battery-life figure than the BTH20’s, though the E700 also takes longer to charge according to the listed specifications. The headphones use Bluetooth 5.1 and support wired listening through a USB Type-C connection. The included accessories list an AUX-to-Type-C cable, a USB-C charging cable, and a carrying case. Buyers who specifically want a standard 3.5 mm headphone jack should note that the E700’s listed jack is USB Type-C.
The E700’s 40 mm dynamic drivers and stated frequency range of 20 Hz to 40 kHz describe its audio hardware, but those figures alone do not settle how it will sound to an individual listener. The over-ear design uses memory foam and faux leather among its listed materials, with metal and plastic also used in the construction. For someone comparing the best rechargeable headband headphones for nurses, this is a rechargeable over-ear option, but the data does not establish sweat resistance or suitability for wearing during clinical work. It is best considered for travel, home listening, or personal use away from work tasks.
Who should skip it: Skip the E700 if a standard 3.5 mm jack is essential, or if you want the faster listed charging time of the BTH20.
Side-by-Side: Which Should You Choose?
• Best for the longer stated battery figure → 1Mii E700. It lists 54 hours, compared with 47.5 hours for the BTH20.
• Best for the shorter stated charging time → iClever BTH20. Its listed charge time is two hours; the E700’s is three.
• Best for hybrid noise cancellation → 1Mii E700. Hybrid ANC is specifically listed alongside active noise cancellation.
• Best for app-based adjustments → 1Mii E700. App control is listed, along with button controls and settings for noise, volume, calls, and voice assistant use.
• Best for Bluetooth version → iClever BTH20. It lists Bluetooth 5.4, while the E700 lists Bluetooth 5.1.
• Best for a straightforward button-control setup → iClever BTH20. Its listed control method is push button, with no app-control feature specified.
• Best for shoppers seeking sweat-resistant true wireless earbuds for nurses → neither. Both are over-ear Bluetooth headphones, and neither data sheet specifies sweat resistance or a true wireless earbud design.
In my opinion, I would choose the iClever BTH20 for a nurse looking for headphones for travel or off-shift listening. Its shorter listed charging time, Bluetooth 5.4, and included 3.5 mm cable make it a practical, flexible pick without leaning on app settings. I’d choose the 1Mii E700 instead if hybrid ANC and app controls matter more than a standard headphone jack. Neither should be treated as a sweat-resistant work headset based on the available specifications.
Before choosing, decide whether you need Bluetooth alone or want a wired option as well. The BTH20’s detachable 3.5 mm cable is the clearer fit if your devices or listening habits call for that connector. The E700 instead lists USB Type-C for wired use and includes an AUX-to-Type-C cable. The connector difference is practical, not cosmetic: check what your intended device accepts before buying.
Next, consider whether you will use app controls. The E700 has a listed app and multiple control categories, including noise and volume. That may be useful if you prefer handling settings from a phone. The BTH20’s listed controls are push buttons, which may appeal if you want fewer control layers. The specifications do not say that either approach is universally easier; the better fit depends on how you prefer to operate headphones.
Battery figures also deserve a careful reading. The E700 has the higher stated average life, while the BTH20 has the shorter stated charging time. Neither figure tells you exactly how long a charge will last in every situation, so treat them as product specifications rather than a guarantee for a particular routine. If minimizing charging interruptions matters most, the E700’s listed battery figure has the edge. If getting back to a charged pair sooner matters more, the BTH20’s listed charging time is shorter.
